How to calculate a Volume of all Cells after using snappyHexMesh

joaquindelpino · August 20, 2017, 18:40

Hello everyone.

I'm simulating a bio-filter inside of a room.
To generate mesh I used snappyHexMesh. Then I runed the simulation using simpleFoam and I got the velocity and pressure in each cell, but now I need to compute the volume of each cell to calculate the % of volume in that velocity is different from zero.

I read a lot of topics in CFD but i don't understand where I must be create codes or use mesh.V().

I would appreciate a detailed explanation

Regards.

Hi Joaquin,

You can have a look at the discussion call "cell volume and face area calculation"
There is a tar.gz with a utility to compute and write V
